The application provides a
laser cladding
lap joint quality control method and device, a storage medium and a terminal, wherein the method comprises the following steps: acquiring an image of a reference stepping area in a previous cladding path to be overlapped with a to-be-cladded path to-be-stepped area, and acquiring
vertical distance data of a
laser cladding
nozzle and the to-be-cladded path to-be-stepped area; based on the image of the reference stepping area and the
vertical distance data, an actual half-width of the reference stepping area is acquired; according to the relationship between the actual half-width and a preset half-width, the position of a cladding center in the
laser cladding
nozzle is corrected based on a preset correction mode, so that the driving
system drives the laser cladding
nozzle with the corrected cladding center position to perform cladding on the to-be-stepped area. The application can realize
dynamic control of the
lap joint rate, and at the same time, conformal cladding of a thin plate is realized, and the cladding quality is higher.
